LATCHING MEANS FOR THE COVERS OF LAUNDRY APPARATUS I Filed March 13, 1928 amewm Patented June 17, 1930 I UNITED STATES JOHN MOSES COFFEE, orcirrirlvnsvinnn, GEORGTA IlA-TGHING MEANS FOR THE COVERS OF LAUNDRY APPARATUS Application filed March 13, 1928. Serial No. 261,294.

This invention relates to laundry apparatus of that'type known-as curb extractors.

An important object of the invention is to provide latching means for the cover for a curb extractor which will permit the cover to be readily appliedto and removed from the machine without damage to the operator or to the clothing being treated.

This object I attain by the construction shown in the accompanying drawing, wherein'for the purpose of illustration is shown a preferred embodiment of my invention and wherein f Figure 1 is a vertical sectional view through the upper end of a curb extractor showing a cover secured thereto in accord ance with my invention;

Figure 2 is a plan viewof the cover in ap plied position; a

Figure 3 is a sectional view on the line 33 of Figure 2. i

Referring now more particularly to the drawing, the numeral 10 generally designates a cover of substantially the same diameter as the frame opening 11 of the curb extractor and having at its sides an upstanding rim 12, the'upper end of which has an out-turned flange 13 adapted to seat upon the upper surface of the curb of the extractor and support the lid. This rim is provided at circumferentially spaced points with openings ltthrough which extend the outer ends of radial llatch bars 15, the inner ends of which are extended through guides 16 carried by the cover. Each latch bar 15 is provided intermediate the rim and. the guide with which it is associated with an upstanding lug 17. The cover is provided centrally with a handle 18 forming a rotatable-mounting for an operating disk '19., This operating disk-has spirally extending slots 20 correspondinginnumber and arrangement to the latch bars and is provided with a small handle21whe'reby it maybe rotated. As this .diskis rotated the latch bars, the lugs 17 of which project into the slots 20, are either projected or retracted,de pending upon the direction of rotation. The. handle 21 which rests upon the cover 10 when the latch bars 15 are in retracted posithe'cover 10 when the tion extends through the operating disk and is constantly urged downwardly by a'spring 22. The lower end of this handle isin the form of a bolt and enters an opening 23 in latch bars are fully projected. v 1

It will be obvious that inorder to apply the cover, it is simply I necessary to place the same in position withthe flange 13 seated upon the curbof the extractor and rotate the, disk 19 to cause the latch bars to project when the outer ends thereof will engage under the curb and coact with the flange to pre vent vertical displacement of the cover.

At this time, the lower end of the handle 21 will be alignedwith the opening sorthat I when the handle .is released, it will come into latching engagement with the cover and accidental displacement of the latch barsis thereby prevented. To release the cover, it is simply necessary to elevate the handle 21 slightlyand then reverse the rotation ofthe control disk.

'- Since the constructlon hereinbefore set forth is'capable of a certainrange of change and modification without materially depart-' ing from the spirit ofthe invention,'I do not limit myself to such specific structure except :as hereinafter claimed. i

the rim of the curb, a disc rotatable upon the,

plate, connections between the disc and the latch bars to permit the turning ofthe former toshift the latter, and a handlefor turning the disc and engaged in the open ing in the plate whenthe bars are in extended position, saidfhandlebeing slidably V directed through the disc. I
